Great tool for measuring tds.
Always wondered about our city water supply. This tool shed a clear light on how unsatisfactory our water really is. We bought a reverse osmosis filter and went from 250 tds to 20 tds. We use this tool regularly now. Extremely happy with this purchase.

Funcional
Se ve de buena calidad. Las instrucciones no estaban tan claras pero logré entender que si enciende en verde es buena calidad para el agua.

Great sensor for checking water quality
Works as intended. Great quality materials used. Great for measuring TDS in water, if you’re using it to double check RODI filter performance, this works perfectly.

Great Tester
This is a great little tester that works very well. I initially thought it was inaccurate, but after researching how TDS meters work I found that water temperature affects the readings. Once I controlled that variable I found that the readings are stable and my water is unfortunately very high. So Iâve gone down the research rabbit hole again for a water filtration system. This product will likely make my family healthier in the end. Thank you Sim Pure!

Quick and accurate
This Simpure tester provides very rapid and accurate readings, and comes plastic container that protects it well.The 3 photos show show results for our tap water (229 ppm here, up to 278 at other times); filter using a Brita Stream (165 ppm); and for water treated by our Simpure countertop reverse osmosis system (1 ppm).My only complaint involve the instructions. They are written in awkward and grammatically incorrect English. Moreover, nowhere does it state the desired levels. The product page has a decent chart of the various ranges. Something similar should have been included.

Impressive Digital Water Tester
I am super impressed with the range of capabilities this tester offers. It was up and running right out of the box and accurately measured the ppms of my tap and filtered water. Since the unit has a glass sensor, which can be easily damaged, I stored it in my top cabinet, away from high-traffic areas.

Up and running within a minute
Great water tester, easy to setup and use. Reading is pretty instant and buttons are large enough to not fumble around.
